When a whale, therefore, desires food, it opens its colossal mouth, and a host of these organisms is, as it were, swept up by the great expanse of the lower jaw: as the mouth closes, the water is ejected, and the life it contained is imprisoned by the appliance we have attempted to describe.
If we consider the number of whales found in the Northern seas, and the mighty bulk of each individual, our imagination entirely fails to appreciate the countless myriads of minute organisms which must be sacrificed to their due nourishment.
One of the principal products of the Greenland whale is its baleen, or whalebone, with the domestic uses of which our readers will be familiar; but the large quantities of oil which it yields are still more valuable. A whale sixty feet in length will supply fully twenty tons of pure oil.
Besides the common whale, our hunters find in the seas of the North the razor-backed whale, or northern rorqual (Balænoptera physalis), characterized by the prominent ridge which extends along its mighty back. This monster of the deep attains a length, it is said, of one hundred feet, and measures from thirty to thirty-five feet in circumference. But its yield of oil and baleen is less than that of the right or Greenland whale, and as its capture is a task of difficulty and danger, the whalers seldom attack it. In its movements it is more rapid and restless, and when harpooned it frequently plunges downward with such force and velocity as to break the line. In several respects it differs from the Greenland species; and particularly in the nature of its food, for it feeds upon fishes of considerable size.
Some of our naturalists affirm that several species of rorquals exist in the Arctic seas; and the pike whale, so called from the resemblance of its mouth to that of a pike, is frequently described as an independent species. Others, however, are of opinion that the pike is simply the young of the monster we have been describing. The rorqual is very voracious, and preys extensively upon fishes; as many as six hundred cod, to say nothing of smaller “fry,” having been found in the stomach of a single individual.
While the Greenland whale is being rapidly driven back into the icy wildernesses beyond Behring Strait, on the west, and the creeks and gulfs beyond Baffin Bay, on the east, the rorquals, including the Balænoptera rostratus (or beaked whale), Balænoptera musculus, and Balænoptera boöps, still frequent the open waters,—their pursuit being, as we have shown, more difficult and less profitable. They are generally found in attendance on the herring-shoals, of which they are the assiduous and destructive enemies. Off Greenland, Spitzbergen, and Novaia Zemlaia they are found in considerable numbers.
Our whalers go forth every year in well-provided ships, and supplied with the best and most formidable weapons which scientific ingenuity can devise. Still they find the enterprise one of peril and hardship, and it is universally recognized as requiring in those who embark in it no ordinary powers of endurance, as well as courage, patience, and perseverance. Yet the Asiatic and American tribes do not fear to confront the ocean-leviathan with the simplest of arms. The Aleüt embarks in his little skiff, or baidar, and catching sight of his prey, stealthily approaches it from behind until he nearly reaches the monster’s head. Then he suddenly and dexterously drives his short spear into the huge flank, just under the fore fin, and retreats as swiftly as his well-plied oars can carry him. If the spear has sunk into the flesh, the whale is doomed; within the next two or three days it will perish, and the currents and the waves will hurl the vast bulk on the nearest shore, to be claimed by its gallant conqueror. And as each spear bears its owner’s peculiar mark, the claim is never disputed.
Occasionally the baidar does not escape in time, and the exasperated leviathan, furiously lashing the waters with its tail, hurls the frail boat high up into the air, as if it were a reed, or sinks it with one crushing blow. No wonder that those of their race who undertake so hazardous a calling are held in high repute among the Aleüts. To sally forth alone, and encounter the whale in the icy waters of the Polar Sea, is a task demanding the utmost intrepidity and the utmost tranquillity of nerve.
Many of the whales thus daringly harpooned are lost. It is on record that, in the summer of 1831, one hundred and eighteen whales were struck near Kadjack, and of these only forty-three were found. The others either drifted to far-off shores and lonely unknown isles, or became the prey of sharks and ocean-birds. Wrangell states that of late years the Russians have introduced the use of the harpoon, and engaged some English harpooneers to teach the Aleüts the secret of their craft; and, therefore, the older and more hazardous method, which the Aleüts had learned from their forefathers, will soon be a thing of the past.
